Recent versions of the Docker CLI support the prune option in different
flavors to keep the system clean.

If your disk capacity is exceeded by Docker’s data folder (e.g.
/var/lib/docker) it’s time to cleanup at least the images and this is much
more comfortable than usage of filters and pipelines in the past.

If you want to play modern Minecraft ModPacks on
CurseForge in Java on Linux, the
Twitch Launcher for Windows is not very helpful.

But since the project artifacts are available for public download and the data
format is pretty straightforward, it was not a big deal to script a download
of all files. I have chosen an Ansible Playbook for this task.

If you want to reduce your nginx logs to non-personalized resp. anonymized
client addresses, you may apply the following method, running a slightly
changed log format after setting a new variable $remote_addr_anon.

I managed to open the SIM slot of the phone and inserted a working SIM
from another phone. Since the SIM was not detected at all, I decided to give
the nightly CynogenMod 12.1 on the phone. Again via SFTP to
SSHDroid in the LAN.

An Optimus G E975 (Intl) was still waiting for wakeup, but official
updates stuck at Android 4.4.2.

So I applied CyanogenMod to that phone and since it was not that easy to
gather all the necessary information, I write down a short protocol of the
steps, that helped in my case. I started with the rather incomplete (with
respect to rooting and recovery) howto at wiki.cynogenmod.org.
